biao-shen — Sat, 22 Feb 2020 07:13:58 GMT

My PIX 520 restart automatically several times a day. what's the possible reasion?

previously ,we use aaa authentication include any any , it authentication tcp only , it work well ,

now we use aaa authentication match and access-list to authentication the UDP, but pix 520 restart automatically several times a day.
